I've seen bug like this before, since an older version of this MOD was not deleted. Make sure to delete all older versions.
If that's not the problem, post more detail here, your OS, civ5 version, DLCs you have, other MODs actived, and if you can use SDK, the live tuner output of LUA error
I never had the mod before today, so previous versions aren't it.
I'm on Windows 8, with Gods&Kings on Steam, with the DLCs Denmark, Korea, Mongols, Polynesia, Bablyon Nebuchadnezzar II, Explorer's Map pack, Cradle of Americas, Asia, Mediterranean, Mesopotamia, and Ancient Wonders. I've tried HotTK with no other mods activated. I am unfortunately unfamiliar with SDK
edit; I actually had the Wonder Splashes enabled, and upon trying it without that it seems alright, at least at first blush.
